Paul Hembery on Friday insisted Pirelli can not take all the blame for the tyre-exploding chaos of last weekend's British grand prix.

Some teams had hit back at their Italian supplier, after Pirelli pointed the finger at those running extreme tyre pressures, wheel cambers and swapping rear tyres left to right.

"Just to be clear," McLaren team boss Martin Whitmarsh told Britain's Sky on Friday, "we always ran within the correct pressures and the correct cambers and everything we did was agreed with Pirelli."

It's on Whitmarsh's last point that Pirelli boss Hembery does take some blame -- the tyre-swapping, which teams reportedly discovered could add 20 per cent to the tyres' lifespan.
